• Envelopes with a peel-off adhesive strip or with more than one
flap that folds over to seal must use adhesives compatible with
the machine’s fusing temperature for 0.1 second (about 170°C
(338 °F)). The extra flaps and strips might cause wrinkling,
creasing, or jams, and may even damage the fuser.

• Do not leave unused transparencies in the paper tray for long.
Dust and dirt may accumulate on them, resulting in spotty

• To avoid smudging caused by fingerprints, handle them
carefully.

• To avoid fading, do not expose printed transparencies to
prolonged sunlight.

• Ensure that transparencies are not wrinkled, curled, or have any
torn edges.

laser printers.

- Curl: Must lie flat with no more than 13 mm of curl in any

direction.

- Condition: Do not use labels with wrinkles, bubbles, or other

indications of separation.

• Make sure that there is no exposed adhesive material between
labels. Exposed areas can cause labels to peel off during printing,
which can cause paper jams. Exposed adhesive can also cause
damage to machine components.

• Do not run a sheet of labels through the machine more than
once. The adhesive backing is designed for only a single pass
through the machine.

• Do not use labels that are separating from the backing sheet or
are wrinkled, bubbled, or otherwise damaged.

• When selecting labels, consider the following factors:

- Adhesives: Should be stable at your machine’s fusing

temperature. Check your machine’s specifications to view the
fusing temperature (about 170°C (338°F)).

- Arrangement: Only use labels with no exposed backing

between them. Labels can peel off sheets that have spaces
between the labels, causing serious jams.

• In the software application, set margins at least 6.4 mm (0.25
inches) away from the edges of the material.

Preprinted paper

When loading preprinted paper, the printed side should be facing up
with an uncurled edge at the front. If you experience problems with
paper feeding, turn the paper around. Note that print quality is not
guaranteed.

• Must be printed with heat-resistant ink that will not melt,
vaporize, or release hazardous emissions when subjected to the
machine’s fusing temperature for 0.1 second (about 170°C
(338°F)).

• Must be non-flammable and should not adversely affect machine
rollers.

• Before you load preprinted paper, verify that the ink on the paper
is dry. During the fusing process, wet ink can come off preprinted
paper, reducing print quality.

When the toner cartridge is near the end of its life:

• White streaks or light printing occurs and/or density variation

•The Status LED blinks red.

If this happens, you can temporarily improve print quality by
redistributing the remaining toner in the cartridge. In some cases,
white streaks or light printing will still occur even after you have
redistributed the toner.

Open the front cover and pull the toner cartridge out.

toner evenly inside the cartridge.

If toner gets on your clothing, wipe it off with a dry cloth and

If printing quality problems occur or if you use your machine in a
dusty enviroment, you need to clean your machine regularly to keep
it in the best printing condition and use your machine longer.

• Cleaning the cabinet of the machine with cleaning
materials containing large amounts of alcohol, solvents, or
other strong substances can discolor or distort the
cabinet.

• If your machine or the surrounding area is contaminated
with toner, we recommend you use a cloth or tissue
dampened with water to clean it. If you use a vacuum
cleaner, toner blows in the air and might be harmful to
you.

Cleaning the inside

During the printing process, paper, toner, and dust particles can
accumulate inside the machine. This buildup can cause print quality
problems, such as toner specks or smearing. Cleaning the inside of
the machine clears and reduces these problems.

Turn the machine off and unplug the power cord. Wait for the

machine to cool down.

Open the front cover and pull the toner cartridge out. Set it on

touching this area.

With a dry, lint-free cloth, wipe away any dust and spilled

Tips for avoiding paper jams

By selecting the correct media types, most paper jams can be avoided. To avoid paper jams, refer to the following guidelines:

• Ensure that the adjustable guides are positioned correctly (see "Tray overview" on page 27).

• Do not overload the tray. Ensure that the paper level is below the paper capacity mark on the inside of the tray.

• Do not remove paper from the tray while your machine is printing.

• Flex, fan, and straighten paper before loading.

• Do not use creased, damp, or highly curled paper.

• Do not mix paper types in a tray.

• Use only recommended print media (see "Print media specifications" on page 79).

This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from

Canadian radio interference regulations

This digital apparatus does not exceed the Class B limits for radio
noise emissions from digital apparatus as set out in the interference­causing equipment standard entitled “Digital Apparatus”, ICES-003
of the Industry and Science Canada.

Replacing the fitted plug (for UK only)

Important

The mains lead for this machine is fitted with a standard (BS 1363) 13
amp plug and has a 13 amp fuse. When you change or examine the

15

fuse, you must re-fit the correct 13 amp fuse. You then need to
replace the fuse cover. If you have lost the fuse cover, do not use the
plug until you have another fuse cover.

Contact the people from you purchased the machine.

The 13 amp plug is the most widely used type in the UK and should
be suitable. However, some buildings (mainly old ones) do not have
normal 13 amp plug sockets. You need to buy a suitable plug
adaptor. Do not remove the moulded plug.

If you cut off the moulded plug, get rid of it straight away.

You cannot rewire the plug and you may receive an electric
shock if you plug it into a socket.
